The injury occurred in Boca’s game against Defensa y Justicia, which they won 2-1.

The winger will be out for at least three weeks and therefore will not be not be able to join up with the national side for their tour of the United States ahead of the Copa America.

Gago has been a key player in his side’s strong start to the season, and not having him for the remaining Copa Libertadores group games will be a huge blow. The only good news for boss Arruabarrena is that Pablo Perez is now fit again, and it is also expected that within a week Adrian Cubas will return.

Boca’s next game is a trip to Venezuela to face Zamora n the Copa Libertadores on Wednesday night.
